• What is the best way to optimize a SQL query: call a function or doing a join?

  Hi, I want to know what is the best way to optimize a SQL query, call a function inside the SELECT statement, or make a simple join?

  It depends on.  Could be a.  Could be the other.  Could be no difference.  You would need to compare with your tables in your environment with your settings.

  If you put a gun to my head, I was given no other information and required that I answered the question, I would tend to wait that the join would be more effective.  In general, if you can do something in pure SQL, it will be more effective than if you call PL/SQL.

• What is the best way to run DAQ in larger system?

  I have a relatively simple installation of the PXI hardware require software in real time to perform data acquisition and to provide feedback to the user.  Somewhere on the order of discrete outputs 150, 55 entered discrete, some analog, etc...  My question is this: does anyone know of a white paper, etc., which describes the best way to the acquisition of configuration data?  For example, is it better to put all the discrete outputs on a single task and manage state in memory (150 items Boolean) before writing to DAQmx, or is there some advantage at the time of the execution/memory to open a task for each channel and individually each signal.  The driver even allow me to do this?

  Synchronization is not a concern, is pilot crashes, so I would like to get the best performance out of DAQmx.

  If someone has explored this?

  Dan

  Hi Dan,.

  To optimize your application, you'll want to create tasks as little as possible.  When you create a task, you ask for all the parameters of this task (which would be like doing 150 calls to the hardware).  The extent of the GB whitepapers - you can find useful this webcast .  For example, some of your concerns are addressed low toware of this FAQ document.  Hope this helps, let me know if you need something more specific.  Have a great day!

• The ultimate way to optimize SQL statements?

  Hi all

  I hope that this discovery you in a good mood

  I have a few SQL I need to optimize.

  In your experience what is the best way to find all the bottlenecks 'True' in the SQL itself.

  It's my workflow:

  Step 1:

  Explain the plain: find all the analyses of full Table right at the front.

  Step 2:

  Run the SQL through Grid control at the place where you can just "run" SQL here.

  Step 3:

  Create a SQL Tuning with the SQL Code that has just been executed.

  Step 4:

  Run SQL Access Advisor and use the SQL code that has just been run.

  Step 5:

  To run the SQL SQL Tuning Advisor.

  I know there are several way to do it, but what is your "workflow."

  Thanks for any help...

  Thank you

  Lady Allora.

  I was approached by one of the Dev and he asked me to run faster than 5 minutes.

  OK - but it is an ARTIFICIAL target and is NOT necessarily realistic or feasible.

  This makes it a RESEARCH project. You are looking for, you analyze, you try to determine if this goal is realistic or even possible.

  There is only one table that has rows 3 million inside and they do a "union all" join on tables that have a few hundred thousand lines in them.

  This means that EACH of the queries in this "union all" can be considered as a separate entity. You can take each of the queries ONE AT A TIME and determine:

  1. how many lines it can return

  2. what execution plan used

  3. what indexes and statistics are available. Are there stats? They are up to date? How they were collected?

  4. that if whatever, in execution plans seems out of the ordinary - perhaps an index is used when it shouldn't, perhaps an index is NOT used when it is possible, perhaps a clue is needed

  All this is LOOKING. As others have said if you know how many rows in the table, how many need to be returned and indexes are available, you can estimate the time MINIMUM it would take to get them. No matter what you do you will not get any faster than that.

  And for a UNION ALL of four motions operation, you can add these 4 'planned' to get the time MINIMUM it might take. That becomes your time back as LOW as POSSIBLE.

  If it is greater than the target, your goal is NOT possible.

  Ok, so many people say over and over again and more than a presence FULL ACCESS TABLE in the plan to explain is not bad.

  NO! This is NOT what they say. You wrong interpret what they tell you.

  Full scans are NOT NECESSARILY bad. Same 14 of them are NOT NECESSARILY bad. One or more of them COULD BE bad or even all of them could be bad.

  They tell you not to make the assumption that a FTS in the plan is bad. Are not these analyses and make the research/control over them, but what you do NOT assume that you must try to eliminate one or all of them.

• The best way to migrate data... Opinion please...

  Guys,

  I'm working on a solution for a customer who needs to move in a new SAN SAN data.

  Existing SAN is attached to the ESX server farm and is very close to the location of a new SAN. In your opinion, what is the best way to move data without interruption to VM ESX farm?

  I know we can do SAN replication, but right now, I don't know if the SAN is still the same provider.

  I know we can do Storage VMotion. In this case, he should present the new SAN somehow for the existing ESX servers.

  I know that we can probably use the converter to migrate virtual machines. This can take some time because we would go over WAN.

  What are your thoughts?

  Thanks in advance for your comments!

  With 4 TB of data, I wouldn't pass on the replication SAN or WAN solution of optimization of the property, and it can fly quickly with 4 TB of data that you use storage vmotion which basically depends on how your WAN links are, if if its quick to go for it.  There is not another free solution then this but if you can manage somehow to make backup of system state of all virtual machines, and then you can ship these backup data to remote locations and import, save back to clusters.  You have to do the actual calculation how fast you can Transfer data from the siteA-> siteB Mbps?  This will give you a clearer picture of how long it will take and picture plan here.  I could do that during maintenance or weekend windows that are the least impact to users and systems.

  If you found this information useful, please consider awarding points to 'Correct' or 'useful '. Thank you!!!

• What is the best way to buy an iPhone Unlocked 7?

  Hi all

  I am currently using T-Mobile and want to get the new iPhone 7. Since there is no option for a sim-free iPhone, what is the best way to buy the new iPhone? Should I get the T-Mobile one full fare? I know that he will be released version but it will come with a T-Mobile sim so what will do with the sim card? Put it away or give it to T-Mobile? Or should I wait for the version without card sim to appear, which I don't think that will come out until November, and I don't want to wait that long.

  Thank you in advance.

  If you do not want to wait to pay full price for the model from T-Mobile.  You can do whatever you want with the SIM card.

• Cannot repair the photo library. The best way to restore from iCloud library?

  The photo library of the system is damaged and cannot be repaired.

  It is said "Photos has attempted to repair the library"Pictures Library 2015 ", but can not open it." .

  
  

  I first met problems with this library a week before and at the time where I could repair and open the library successfully, but lacked a month value of photos.

  Given that it was successfully in the iCloud library, I left it to re - sync - but this process suspended several times before the end, and the photo library of the system now seems to be permanently damaged.

  I have no project of marked or impression of faces in the photo library of the system, then I would be happy just to restore from iCloud.

  My plan is to put in place a new - empty - library and then that designate the library of the system.

  If I understand this right, the new (empty) system Photo library will now resynchronize with iCloud and will copy all the contents of this library of back to my Mac.

  Is this correct? It is the most effective way to restore my library?

  And while I'm here - what is the best way to manage a very large library? I had my photo library become corrupted ten three or four times over the past years and have found it necessary to divide into single years to prevent this. I overlooked this piece of household by the end of 2015, and now it's happened again... Surely, there must be an easier way to manage libraries of images of several years?

  Is this correct? It is the most effective way to restore my library?

  Yes, if you don't have a useful upward on your Mac.

  How do you call a large library, I've never had a corrupt Library, I think that your problems are not the result of the size of the library, but rather something else. From my experience it is recommended to maintain a local upward, I use Time machine, but also have a second to the top using a third-party backup solution.

• What is the best way to import my address and e-mail of Pegasus in Thunderbird?

  I use Windows 7 x 64. I have a number of files and many electronic addresses in the Pegasus Mail client. I'm looking to migrate to Thunderbird. Can you tell me the best way to move my files to Thunderbird?

  Thank you
  Allen Hill

  For your address books, can export you to a format such as CSV?

  To move e-mail messages, the cleaner is to use the IMAP protocol. Then your new client look just the same files you had in Pegasus.

  Unfortunately, email clients tend to use their own systems of storage of e-mail owner and there is no commonly used standards that could help to transfer between clients. If you can export files in mbox format, then Thunderbird can use.

  Archive messages or move them to some other local mailboxes or mailboxes on the server. Don't know what you are trying to do because it appears that you have 2/3 of your hard disk.

  Why do you think archiving emails in 2 places? Where are you trying to save space to?
